20090241301 | TOOL ASSEMBLY USED WITH FRICTION STIR WELDING - A tool assembly which is particularly suitable for friction stir welding applications. The tool assembly includes a holder having an axis and one end adapted to be rotatably driven by a rotary drive mechanism about the holder axis. A tool having an axis is also provided and includes a tool tip at one end. A fastener detachably and coaxially secures the holder and tool together. This fastener includes a first part secured to the second end of the holder and a second part secured to the second end of the tool. | 10-01-2009 |
20100242916 | FUEL SYSTEM FOR A DIRECT INJECTION ENGINE - A fuel delivery system for a direct injection internal combustion engine which reduces mechanical stress on the fuel system components. The system includes a first and a second fuel rail mounted to the engine block for the internal combustion engine. A device is attached to the fuel rails which reduces movement of the fuel rails relative to the engine block and mechanical stress that would otherwise result from such movement. | 09-30-2010 |
20100244440 | HIGH PRESSURE FUEL PIPE CONSTRUCTION FOR AN INTERNAL COMBUSTION ENGINE - A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop. | 09-30-2010 |
20110217186 | FUEL PUMP - A high pressure fuel pump for use with a direct injection engine having a housing which defines a pump chamber. A port is formed in the housing which fluidly connects a fuel in the passageway with the pump chamber. An elongated valve is movably mounted within the housing between an open and a closed position. In its open position, the inlet passageway is fluidly connected with the pump chamber while, conversely, in the closed position the fuel valve blocks the fluid flow between the inlet passageway and the pump chamber. A circuit controls the deceleration of the valve to reduce pump noise. | 09-08-2011 |
20120006914 | HIGH PRESSURE FUEL PIPE CONSTRUCTION FOR AN INTERNAL COMBUSTION ENGINE - A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop. | 01-12-2012 |
20120070012 | NOISE REDUCTION SYSTEM FOR AN ELECTRICALLY POERED AUTOMOTIVE VEHICLE - A noise reduction system for an automotive vehicle powered at least in part by an electric motor located separately from the passenger compartment. The system includes at least one sensor which produces an output signal having a frequency, amplitude and phase representative of noise generated by the electric motor. At least one speaker is positioned closely adjacent the electric motor. A speaker output controller receives the output from the sensor as an input signal and generates an output signal to the speaker so that the speaker produces an audible signal having substantially the same frequency and amplitude but inverted in phase relative to the output from the sensor. | 03-22-2012 |
20130074804 | FUEL DELIVERY SYSTEM - A fuel delivery system for a direct injection internal combustion engine having two fuel rails and a plurality of fuel injectors attached to and fluidly connected with each fuel rail. A first fuel pump has its output connected with the first fuel rail while a second fuel pump has its output connected with the second fuel rail. A crossover pipe fluidly connects the outlets of both the first and second pumps. Both the first pump and the second pump each have an intake stroke and a pumping stroke. Furthermore, the intake stroke of the first pump coincides with the pumping stroke of the second pump and vice versa. | 03-28-2013 |
20140299102 | FUEL DELIVERY SYSTEM - A fuel delivery system for a direct injection internal combustion engine having two fuel rails and a plurality of fuel injectors attached to and fluidly connected with each fuel rail. A first fuel pump has its output connected with the first fuel rail while a second fuel pump has its output connected with the second fuel rail. A crossover pipe fluidly connects the outlets of both the first and second pumps. Both the first pump and the second pump each have an intake stroke and a pumping stroke. Furthermore, the intake stroke of the first pump coincides with the pumping stroke of the second pump and vice versa. | 10-09-2014 |
20140314603 | FUEL PUMP - A fuel pump having a housing which defines a pump chamber with an inlet and an outlet. A piston is reciprocally mounted in the pump chamber. An inlet valve is mounted fluidly in series between the pump chamber and the housing inlet which opens and closes the inlet in synchronism with the reciprocation of the piston. A rotary valve is mounted fluidly in series with the housing outlet and the rotary outlet valve is rotatably driven in synchronism with reciprocation of the piston. The rotary valve is configured so that it is fluidly open only at one or more predetermined angular positions of the rotary outlet valve. The open and close timings of the rotary inlet and outlet valves are completely controlled by a motor in order to control the fuel pressure, especially to avoid excessive fuel compression and resulting fuel pressure fluctuation. | 10-23-2014 |
